3 Claims.

My invention relates to improvements in paper roll holders adapted forholding rolls of toilet paper and paper towels.

The object of my invention is to provide a roll holder with means forretarding the unrolling of the paper without limiting the rotation ofthe roll of paper to one revolution, or to a fraction of a revolution.

A further object is to provide novel means upon the roller, or mandrel,carrying the roll of paper, for insuring the roll of paper and theroller, or mandrel; turning together.

A further object is to provide brackets upon which the roller, ormandrel, carrying the roll of paper, is mounted for rotation, andconstruct one of the brackets with friction means adapted for engaging acam secured upon the roller and thereby retarding the rotation of theroller for preventing the paper from unrolling too freely.

A further objectis to provide means for normally positioning the roll ofpaper so that a strip of paper may be readily torn from the roll.

A further object is to construct a paper roll holder which is simple inconstruction and which can be manufactured at a low cost, and whicheliminates the objectional features usually found parts, which will behereinafter more fully described and claimed, constitute my invention.

Referring to the accompanying drawing:

Fig. 1 is a transverse vertical section, as on line ll, Fig. 5, showingmy novel paper holder.

Fig. 2 is a perspective View showing one end of the roller, or mandrel,for carrying the roll of paper.

Fig. 3 is a perspective view showingthe inner face of one of thebr'acketsadapted for receiving the end of the roll shown in Fig. 2, andshow ing a spring mounted upon the bracket.

Fig. 4 is a perspective View of the spring; detached.

Fig. 5 is a vertical longitudinal section, as on line 55, Fig. 1.

In the drawing, in which like'reference characters refer to like parts,6 represents my novel holder for supporting a roll of paper 1. Theholder 6 comprises brackets 8 and 9, adapted to be secured to a wall, orother suitable support, by fastening devices l0.

' A roller, or mandrel, I2 is provided with stud shafts l3 and M, whichshafts are adapted to be rotatably mounted upon the brackets 8 and 9.The roller [2 is of such diameter that it will freely enter thepaper'tube I6, upon which the strip of paper 15, forming the roll I, iswound, with the inner end of said strip" pasted to the tube I6, so thatthe latter will'rotate with. the roll 1. V

The roller 12 is provided with friction means,

in the form of a spring l8, for insuring the roll 'I rotating with theroller l2. The spring I8 is mounted upon the rollerl2 in a' novelmanner. The roller. I2 is provided with a longitudinal slot l9, havingundercut end chambers 20, as shown in Fig. 5, adapted to receive theends of the spring I8. p

The spring 18 may be formed of round spring wire and provided with 'abowed central portion 2|, which portion 2| is held in aradial positionupon the roller [2, for engagement with the tube I6, by radiallyextendin'g walls 22, of the roller l2, which walls 22 define the slot I9. The spring l8 may be compressed by the tube [6, as the chambers 29are of 'suflicient lengthto allow the ends of the spring l8 to slideinto the chambers 20 when the spring is compressed by the tube I6. Noother fastening means are necessary for retaining the spring l8 upon theroller 12.

The novel construction of the bracket 9 and the roller I2 is as follows:The bracket 9 is provided with an aperture25, in which'the outer end ofthe shaft [4 is mounted for rotation. The shaft l4 and the roller l2 maybe readily mounted'upon the bracket 9 as the bracket 8 is provided withthe usual form of open vertical slot jacent to the end of the roller 12from which the,

shaft it extends. The bracket 9 is provided with a recess 29, formedupon the inner face thereof to receive the cam 28 and allow the latterto freely rotate with the shaft M. A spring 30 is mounted upon thebracket 9 and extends into said recess 29 and is adapted to be engagedby the cam for retarding the rotationof the roll I, when the free end I5of the paper strip is pulled, or suddenly jerked, with more force thanis necessary for removing a small quantity of paper from the roll.

The spring 30 is constructed of flat spring metal, having a straightbody portion 3| and a rounded end portion 32, which latter occupies therecess 29 and is positioned to be engaged by the cam 28. The bracket 9is provided upon its inner face witha slot 33 for receiving said bodyportion 3| of the spring 30. The bracket 9 is also provided with arecess 34 for the insertion of the reduced shank 95. formed upon the endof the body portion opposite to the rounded end portion 32. Said bodyportion 3| is provided with a hole 36 for the passage of a screw 31,adapted for retaining the spring 30 upon the bracket. The bracket 9 isalso provided with an enlarged recess 38, which is occupied by therounded end portion 32 of the spring 30, to permit the spring to yieldsufliciently to allow the cam 28 to deflect the spring and pass over therounded end portion 32, when the roll 1 is rotated by the pulling of thepaper strip l5.

When the cam 28 ha passed the Spring 30 the roll -l may be turned freelyfor nearly a revolution to permit a short strip of paper to be drawnfrom the roll I. The roller I2 is provided with a weight 40, locatedadjacent to the radial position of the cam 28, relatively to the rollerI2. The weight 40 tends to position the roller l2 so that it will have afree movement throughout a portion of its revolution before the cam 28engages the spring 30, thus insuring a free movement of the roll I whenthe free end of the strip is first pulled to rotate the roll;

In the operation of the paper roll holder, the spring 3!! engages thecam 28 and the spring exerts sufficient resistance to the rotation ofthe cam to prevent the roll I from spinning and unrolling the paper to alength greater than the circumference of the roll.

Various changes in the construction and arrangement of the parts may bemade without departing from my invention.

I claim:

l. A paper roll holder including a bracket adapted to be secured in afixed position, a roller adapted for mounting a roll of paper thereonfor rotation with the roller, a shaft projecting from an end of theroller, said bracket having a recess formed therein for mounting saidshaft for rotation upon the bracket, a cam secured upon said shaftadjacent to the end of the roller, said bracket having an enlargedrecess formed in the face thereof adjacent to the end of the rolleradapted for freely receiving the cam, a plate spring having a flat bodyportion and a rounded end portion, said bracket having a slot formedupon the face thereof presented toward the roller adapted to receivesaid body portion with said rounded end portion occupying said lastmentioned recess and positioned therein for engagement by said cam, andfastening means upon said bracket extending transversely through saidbody portion for securing said body portion within said slot flush withsaid face of the bracket presented toward the roller.

A paper roll holder including a bracket adapted to be secured in afixed position, a roller adapted for securing a roll of paper thereon, ashaft projecting from an end of the roller, said bracket having a recessformed therein for mounting said shaft for rotation upon the bracket, acam secured upon said shaft adjacent to the end of the roller, saidbracket having an enlarged recess formed in the face thereof adjacent tothe end of the roller adapted for freely receiving said cam, a platespring having a flat body portion and a rounded end portion, saidbracket having a slot formed upon the face thereof presented toward theroller adapted to receive said body portion with said rounded endportion occupying said last named recess and positioned therein forengagement by said cam, said body portion having a reduced shankextendin longitudinally from the end of said body portion opposite tosaid rounded end portion, said bracket having a recess occupied by saidshank, and fastening means upon said bracket adapted for securing saidbody portion within said slot flush with said face of the bracketpresented toward the roller.

3. A paper roll holder including a bracket, a roller mounted forrotation upon the bracket, a roll of paper mounted upon the roller, saidroller having a longitudinal slot formed therein, a spring of greaterlength than said slot, said roller having undercut chambers locatedadjacent to the ends of said slot adapted to be occupied by the ends ofthe spring, said spring having a centrally bowed portion normallyextending beyond the cylindrical surface of the roller, said rollerhaving radially extending walls defining said slot and adapted forretaining said bowed portion of the spring positioned radially forfrictionally engaging the roll of paper, and means upon the bracketadapted for engagement with the roller for retarding the rotation of thelatter.
